Using extensive research, interviews with program leaders, and examples, Preventing and Healing Climate Traumas is a step-by-step guide for organizing community-based, culturally tailored, population-level mental wellness and resilience-building initiatives to prevent and heal individual and collective climate traumas.This book describes how to use a public health approach to build universal capacity for mental wellness and transformational resilience by engaging community members in building robust social support networks, making a just transition by regenerating local physical/built, economic, and ecological systems, learning how trauma and toxic stress can affect their body, mind, and emotions as well as age and culturally tailored mental wellness and resilience skills, and organizing group and community-minded events that help residents heal their traumas. These actions build community cohesion and efficacy as residents also engage in solutions to the climate emergency.This book is essential reading for grassroots, civic, non-profit, private, and public sector mental health, human services, disaster management, climate, faith, education, and other professionals, as well as members of the public concerned about these issues. Readers will come away from this book with practical methods—based on real-world examples—that they can use to organize and facilitate community-based initiatives that prevent and heal mental health and psycho-social-spiritual problems and reduce contributions to the climate crisis.
